As a pension fund manager, you have promised to make perpetual payments of €1mn per year to your beneficiaries. You can invest in the 3-year coupon bond mentioned above (assume duration 2 years) and in a zero-coupon bond (par value = €1000) with a time to maturity of 40 years. Yield to maturity is 4%. How much of each bond will you hold in your portfolio?
Perpetual payments of $1 million
Duration of Perpetuity = (1 + y)/y = 1.04 / 0.04 = 26 years
Equalise the Duration = 26 = (w * 2) + [(1 – w) * 40]
w = 0.3684 | (1-w) = 0.6316
36.84% in the 3-year coupon bond and 63.16% zero-coupon bond
In millions:
0.3684 * 26 million = 9.58 million in the 3-year coupon bond
0.6316 * 26 million = 16.42 million in the zero-coupon bond
In the absence of arbitrage opportunities, expected excess returns of portfolios that are:
a. proportional to its standard deviation.
b. proportional to its beta coefficient.
c. proportional to its weight in the market portfolio.
d. inversely proportional to its standard deviation.
proportional to its beta coefficient.
The term ‘Active share’ was introduced by Cremers and Petajisto. Please explain (in words) the concept of active sharing. In addition, answer the following two questions:
- Did funds with a high active share outperform or underperform the market?
- Which type of mutual funds contributed to the average underperformance of mutual funds as a group, according to Cremers and Petajisto?
Funds with a high active share make ‘active’ choices, meaning they pick just a handful of stocks within an industry. Funds with a high active share outperformed others. Underperformance was driven by index huggers and market timers
Assume that the single index model holds and that you held the (well-diversified) market portfolio with a very large number of securities. If the standard deviation of your portfolio was 0.20 and σM was 0.10, the β of the portfolio would be approximately:
a. 1.5
b. 2
c. 1
d. 0.5

XYZ just issued a 5-year bond on which the YTM is 8%. CDS are also traded on this stock. The spread for 5-year protection is currently 500bps. CDS contracts are settled on the basis of cash settlements. Risk-free investments are also possible, with a yield of 2.50% with a flat yield curve. Is an arbitrage strategy possible here? If yes, how do you set it up and what is the profit of the strategy?
Yes, there is an arbitrage opportunity.
Buy the 5-year bond and receive 8%, the CDS (insurance) costs 5%.
The bond with CDS provides a return of 8% - 5% = 3%
Borrow funds by shorting (selling) treasury bill => 3% – 2.5% = 0.5%
Profit from Arbitrage is 0.5%
